Cholinergic structures and neuropathologic alterations in the olfactory bulb of Alzheimer's disease brain samples

This report describes the laminar distribution of acetylcholinesterase-positive structures and the neuropathologic alterations in the human olfactory bulb of control and Alzheimer's disease brain samples. The results suggests that no correlation exists between the distribution of cholinergic axons and the neuropathological alterations in the different layers in Alzheimer's disease.
